dsx1ExtCfgT18ZeroDetect
Module: RFC1406Ext-MIB
OID (symbolic): RFC1406Ext-MIB::dsx1ExtCfgT18ZeroDetect
OID (numeric): 1.3.6.1.4.1.495.2.1.6.53.10.1.54
Node type: OBJECT-TYPE
Type: TimeTicks
Access: read-only
Description: Indicates the total time that 8 consecutive zeros were received on this line interface. If no such event has occurred since system startup, then the value will be zero.
What is dsx1ExtCfgT18ZeroDetect?
This counter tracks the cumulative time during which the interface detected runs of 8 consecutive zero bits in the received T1/E1 signal. Long runs of zeros can starve the receiver's clock recovery circuitry of transitions, so admins watch this counter to catch line-coding or AMI-violation issues before they cause synchronization loss. A nonzero dsx1ExtCfgT18ZeroDetect value on an AMI-coded T1 line would prompt an admin to check whether B8ZS zero-substitution coding should be enabled instead.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.495.2.1.6.53.10.1.54 snmpwalk -v2c -c public <target> RFC1406Ext-MIB::dsx1ExtCfgT18ZeroDetect
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.495.2.1.6.53.10.1.54.1 snmpget -v2c -c public <target> RFC1406Ext-MIB::dsx1ExtCfgT18ZeroDetect.1
